Output Node
The Output node is where image generation actually happens. It receives a prompt and (optionally) one or more source images, runs them through the model you’ve selected, and shows the result.
Targets
- prompt — connect from a Prompt node
- images — connect one or more Image / Output / Video nodes
If you only connect a prompt → text-to-image. If you connect both → image-to-image editing or multi-image fusion (model-dependent).
Picking a model
Each Output node has its own model dropdown. Switching models doesn’t replace the result — it just changes what the next click of Generate will produce.
Common picks:
- Nano Banana 2 — fast, cheap, supports T2I and I2I (8 credits)
- Nano Banana Pro — higher fidelity, longer prompt context
- GPT Image 2 — OpenAI; strong prompt adherence, ultra-wide aspect ratios (5 credits)
- Imagen 4 Ultra — Google’s flagship image model
See Image Models for the full lineup and per-model parameters.
Generating
Click Generate. Banana Flow will:
- Verify you have enough credits
- Send the request to the model provider
- Poll until the image is ready (typically 5–30 seconds)
- Store the result in your Library and display it on the node
Editing the result
Click Edit on the generated image to open the in-canvas editor. Saving spawns a new Image node — your original Output result is preserved.
Bulk generation
There’s no special mode to enable. The moment your connected prompt contains a
{a|b|c} wildcard, the next click of Generate is auto-routed to the bulk
pipeline. The Output node shows a chip below the prompt with the live combo
count and total cost. See the
Bulk Generation tutorial.
